Google is taking artificial intelligence where no company has gone before —outer space. On November 4, 2025, the company announced Project Suncatcher, an ambitious plan to build solar-powered satellite constellations equipped with its Tensor Processing Units (TPUs) to run machine learning models beyond Earth’s atmosphere.
The initial stage is set to commence in early 2027, with Google planning to deploy two prototype satellites in partnership with Planet Labs, a satellite imaging company based in the United States. This mission aims to evaluate if Google's TPUs can withstand the harsh conditions of low-Earth orbit and if optical links between satellites can facilitate distributed AI tasks.
A Leap Into the Future
Led by Travis Beals, Senior Director of Paradigms of Intelligence at Google, Project Suncatcher is described as “a moonshot grounded in data.” Beals says the early analysis shows “no fundamental barriers” preventing space-based AI compute from becoming reality.
“Our TPUs are headed to space,” said CEO Sundar Pichai. “Like any moonshot, it’s going to take years of testing and breakthroughs,” Pichai added. “But our 2027 launch with Planet will be a crucial step toward that vision.” If successful, Project Suncatcher could redefine not just how AI runs but where it lives. For Google, the next frontier of computation might truly be among the stars.
At the heart of Project Suncatcher is a pursuit of limitless solar energy. In orbit, solar panels can generate up to eight times more power than on Earth and operate almost nonstop, cutting battery dependence.
Google envisions compact constellations of interconnected satellites forming what could evolve into data-center-scale compute infrastructure in space, reducing pressure on Earth’s energy resources while unlocking massive processing capacity for AI.
With launch costs expected to fall below $200 per kilogram by the mid-2030s, Google believes space-based data centers could soon rival Earth-based ones as AI power demands soar.
The company’s approach also signals a growing trend. Amazon’s Jeff Bezos has forecasted space-based data centers within two decades, while startups like Starcloud, backed by Google and NVIDIA, are already experimenting in the same direction.
